Tromsø (Northern Sami: Romsa; Finnish: Tromssa; Kven: Tromssa) is a city and municipality in Troms county, Norway. The administrative center of the municipality is the city of Tromsø. Outside of Norway, Tromso and Tromsö are alternative spellings of the city. Tromsø is considered the northernmost city in the world with a population above 50,000. The most populous town north of it is Alta, Norway, with a population of 14,272.
Tromsø lies in Northern Norway. The municipality has a population of 72,066, but with an annual influx of students it has over 75,000 most of the year. It is the largest urban area in Northern Norway and the third largest north of the Arctic Circle (following Murmansk and Norilsk). Most of Tromsø, including the city center, is located on the island of Tromsøya, 217 miles (349.23 kilometers) north of the Arctic Circle. In 2012, Tromsøya had a population of 36,088. Substantial parts of the urban area are also situated on the mainland to the east, and on parts of Kvaløya—a large island to the west. Tromsøya is connected to the mainland by the Tromsø Bridge and the Tromsøysund Tunnel, and to the island of Kvaløya by the Sandnessund Bridge. The city is warmer than most other places located on the same latitude, due to the warming effect of the Gulf Stream.
The city center of Tromsø contains the highest number of old wooden houses in Northern Norway, the oldest house dating from 1789. The city is a cultural centre for its region, with several festivals taking place in the summer. Some of Norway's best-known musicians, Torbjørn Brundtland and Svein Berge of the electronica duo Röyksopp and Lene Marlin grew up and started their careers in Tromsø. Noted electronic musician Geir Jenssen also hails from Tromsø.
The most famous football team in the area, Tromsø IL, currently plays in the Norwegian Premier League.
